{"product_id":"copper-zenith-4000-dual-spring-mattress","title":"Copper Zenith 4000 Dual Spring Mattress","description":"\u003cp dir=\"ltr\"\u003eThe Millie \u0026amp; Jones Copper Zenith 4000 is the top of the Copper range. It doubles the base layer to 2000 full-height pocket springs and adds 2000 micro springs above them, so you get firm support underneath and a surface that follows your shape. Reflex foam, 2cm of memory foam and a copper-infused layer sit on top, under a bamboo knit cover.\u003c\/p\u003e\u003cp dir=\"ltr\"\u003eThe feel is medium-firm: more supportive than the Copper Summit 3000, with the same responsive top. It suits back sleepers and people who want a firmer bed without the hard feel of a traditional firm mattress, and the independent pocket springs keep one sleeper’s movement from travelling across the bed.\u003c\/p\u003e\u003cp dir=\"ltr\"\u003eAt 27cm deep it is a full-depth mattress for a standard bed frame or divan, so choose deep-fitted sheets. It is made in the UK, meets BS 7177 for fire safety and arrives rolled and vacuum-packed. Unroll it on the day it arrives and allow a day or two for it to reach its full shape.\u003c\/p\u003e\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eKey facts\u003c\/strong\u003e\u003c\/p\u003e\u003cul dir=\"ltr\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeel:\u003c\/strong\u003e Medium-firm (7 out of 10)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth:\u003c\/strong\u003e 27cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSprings:\u003c\/strong\u003e 2000 pocket springs, 18cm, with 2000 micro springs above\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComfort layers:\u003c\/strong\u003e Reflex foam, 2cm memory foam and a copper-infused layer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCover:\u003c\/strong\u003e Bamboo stretch-knit, tape-edged\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSizes:\u003c\/strong\u003e Single 90 x 190cm, Small Double 120 x 190cm, Double 135 x 190cm, King 150 x 200cm, Super King 180 x 200cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFire safety:\u003c\/strong\u003e Meets BS 7177\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade in:\u003c\/strong\u003e The UK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArrives:\u003c\/strong\u003e Rolled and vacuum-packed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDelivery:\u003c\/strong\u003e Free to mainland UK, on the date you choose in your basket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGuarantee:\u003c\/strong\u003e 10-year manufacturer’s guarantee\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eWill it fit your bed?\u003c\/strong\u003e\u003c\/p\u003e\u003cp dir=\"ltr\"\u003eChoose the size your bed frame is made for: single 90 x 190cm, small double 120 x 190cm, double 135 x 190cm, king 150 x 200cm or super king 180 x 200cm. At 27cm deep, the Copper Zenith 4000 is for standard beds, ottomans and divans.
